OLS, an acronym for Orientation of the Last Slot, is a last slot method used to skip any OLL case while simultaneously solving the last F2L pair. All OLS cases can be solved using one of the algorithms found in VLS or HLS. If the pair cannot be solved using RUR' or RU'R', it can be intuitively changed to be able to do so. For example, if you were to set up this case (RU'R'URU2R'), the pair can be easily changed to an HLS case by intuitively doing this algorithm (RU2R'U'). This method is quite helpful with decreasing times once the solver gets used to using the algorithms. Some speedsolvers who use this method from time to time include Feliks Zemdegs and Seung Hyuk Nahm.
